Anyone else used the Behringer 8024 RTA ?

[Shabbyroad]

I've just installed a Behringer DSP8024 and hooked up their ECM8000 microphone.
What I'm trying to do is use the Auto-Q function to fire pink-noise into my room with the DSP8024 strapped across the main inserts of my mixer.

The function appears to work ok but I'm surprised at the extremes on the EQ curve that results. Mostly +16 db across pretty much all frequencies above 100Hz - which suggests to me that there are some extremes at other frequencies in the 31 bands that mean most of the pretty flat responding frequencies have to be boosted 16dB to compensate. (my guess)

Are there some rules of thumb for such analysis ? I don't expect to become a professional overnight but could sure use some advice and pointers to first principals on this process.

thanks
